Objectives:
External cervical resorption (ECR) is a progressive condition that may compromise both periodontal and pulpal tissues. This report describes the outcome of a single-session combined endodontic-periodontal approach for the management of ECR in a previously treated maxillary central incisor.
Case Presentation:
A 41-year-old male presented with ECR affecting the maxillary left central incisor, associated with previous trauma, a sinus tract, and defective root canal treatment. Cone-beam computed tomography (CBCT) was used for diagnosis, classification, and treatment planning. A single-session approach combining endodontic retreatment and periodontal surgery was performed.
Results:
At 28 months, the tooth remained asymptomatic and functional, with clinical periodontal stability and radiographic periapical healing. However, no new bone formation was observed in the cervical buccal bone plate, and a residual probing depth of 5 mm persisted without bleeding or mobility.
Conclusions:
A single-session combined approach may be a reasonable option for moderate ECR when adequate access and defect sealing are achievable. In this case, the outcome reflected disease control and structural stability rather than complete tissue regeneration.
